M Dwarf Stars In subject area: Physics and Astronomy M Dwarf Stars are low-mass stars that host closely-packed planetary systems, often with multiple rocky planets. They are known to have a paucity of Jupiter-mass planets and approximately one-third of these rocky planets orbit within the habi...

“If a planet is far enough away from an M dwarf, it could potentially retain an atmosphere. We cannot conclude yet that all rocky planets around these stars get reduced to Mercury’s fate,” Hill said. “I remain optimistic.” With hopeful hearts, we continue to search the sky. While ...
(the thick long-dashed curves in Fig.1), increasing the estimated percentage of stars with HZ-planets to about 100%, namely, one habitable planet per M-dwarf. Excluding binary stars, as it has been argued that the orbits of their planets may be unstable, would lower these numbers by a ...
PTF/M-dwarfs is a 100,000-target M-dwarf planetary transit survey, a Key Project of the Palomar Transient Factory (PTF) collaboration. The survey is sensitive to Jupiter-radius planets around all of the target stars, and has sufficient precision to reach Neptunes and super-Earths for the bes...

The Hubble Space Telescope image on the left is an edge-on view of a portion of a vast debris disk around the young, nearby red dwarf star AU Microscopii (AU Mic), where several "blobs" of material could be "snowplowing" remaining debris out of the system and limiting habitability of ...
M dwarf stars are currently the main targets in searches for potentially habitable planets. However, their winds have been suggested to be harmful to planetary atmospheres. Here, in order to better understand the winds of M dwarfs and also infer their physical properties, we perform a one-...
